The invention belongs to the technical field of ship resistance reduction devices, and discloses a bubble resistance reduction device and a ship. The bubble drag reduction device comprises a gas generator, a bubble generator and a bubble breaker. The gas generator can generate compressed gas. The bubble generator is installed at the bottom of the ship and communicates with the gas generator, and compressed gas generates first bubbles through the bubble generator to be discharged. And the bubble breaker is positioned at the downstream of the bubble generator and is communicated with the bubble generator. The bubble breaker has an open state and a closed state, when the bubble breaker is in the open state, the first bubbles are broken into second bubbles through the bubble breaker, and the second bubbles flow into the bottom of the ship; when the bubble breaker is in a closed state, the first bubbles are directly discharged and flow into the bottom of the ship, the universality is high, and the drag reduction effect is good; structural operation is simple, and cost is low. The ship comprises a ship body and the bubble drag reduction device, and the bubble drag reduction device is located at the bottom of the ship body, so that the ship is high in overall operation efficiency and low in cost.
本发明属于船舶减阻装置技术领域,公开了一种气泡减阻装置及船舶。气泡减阻装置包括气体产生器、气泡发生器和气泡破碎器。气体产生器能够产生压缩气体。气泡发生器安装于船舶底部,并与气体产生器连通,压缩气体通过气泡发生器产生第一气泡排出。气泡破碎器位于气泡发生器下游,并与气泡发生器连通。气泡破碎器具有开启状态和关闭状态,气泡破碎器处于开启状态时,第一气泡通过气泡破碎器破碎变成第二气泡后,第二气泡流入船舶底部;气泡破碎器处于关闭状态时,第一气泡直接排出流入船舶底部,普适性高,减阻效果好;结构操作简单、成本低。船舶包括船本体和上述气泡减阻装置,气泡减阻装置位于船本体底部,使船舶整体运营效率高、成本低。
